ABSTRACT
A 1.5-mile conidor along Palomar Airport Road, between Pasco del Norte and College
Boulevard, was surveyed for cultural resources in June of 1987, This survey resulted in
thc relocation of two previously recorded sites (SDi-8692 and W-117). In November of
1987, engineers from the Qty of Carlsbad redesigned the road improvement area to include
two additional impact areas, one on the west end of the original improvement corridor and
one area, on the east end of die corridor. The westem impact area is on the south side of
Palomar Airport Road, adjacent to Paseo del Norte near the westem boundary of the
improvement area. The eastem impact area is also on die soutii side of Palomar Airport ^
Road, just east of Uurel Tree Lane. Pedestrian survey of these proposed impact areas
resulted in die relocation and enlargement of previously recoided site SDi-10670 (W-117).

INTRODUCTION
1.1 PROJECT DESCRIPTION
WESTEC Services. Inc. conducted a literature review for archaeological resources and
completed a field survey of die original 1.5-mile project corridor in partial fulfillment of
C:EQA requirements (as amended in 1984). in June of 1987 (Cheever and Gallegos 1987).
The addition of two previously unsurveyed impact areas was made in O:tober of 1987.
Archaeologists from WESTEC surveyed diese new areas on October 30.1987.
1.2 PROJECT LOCATION AND ENVIRONMENTAL SETTING
The project is located in the west central region of die City of Carlsbad. The impact areas,
as currently planned, are on die westem end of a 1.5-miIe segment of Palomar Airpon
Road between Paseo del None and CoUege Boulevard (Area 1) and on die eastern end of
die same road segment (Area 2). Botii of tiiese impact areas are on die soudi side of
Palomar Airport Road (Figures 1 and 2).
Area 1 improvements are confined between Station numbers 30-K)0 and 45+00 and range
between 160 to 20 feet in widdi This area, as currentiy planned, wiU be a temporary detour
road. The environmental setting in die vicinity of Area 1 consists of die base of a marine
terrace or ridge diat has been cut by die construction of Palomar Airpon Road. Vegetation
is primarily introduced grasses and herbs and portions of tiie area have been used for
agriculture. Surface disturbance across Area 1 exists in the form of din roads and tire
furrows.
Area 2 is on die soudi side of Paiomar Airpon Road, just east of Laurel Tree Lane. As
currentiy planned, tius area wUl be impacted by construction of a stomi drain. Area 2
includes ponions of relatively fiat canyon bottom, adjacent to a creek. The soil is alluvial
and tiiere are low. marine tcnaces making up tiie remainder of die existing landforms.
Ponions of Area 2 have been disturbed by grading and unautiiorized dumping, while other
areas appear to be undisturbed. The vegetation in the area is characteristic of disturbed
areas generally, consisting of non-native herbs, grasses, and diisties. However diere are
stands of Coast Live Oak and Elderberry trees in die undisturijcd ponions of die impact
area.

BACKGROUND INFORMATION
2.1 CULTURE HISTORY
In prehistoric tinies. the Carlsbad area was occupied by at least three, somewhat distinct
culture groups. These people are Icnown as the San Dieguito, La Jolla. and Luiseno
Native American people have occupied San Diego County from approximately
10.000 years ago through the present day. A detailed culture history of San Diego County
IS available upon request from WESTEC Services. Inc.
2.2 RECORD SEARCH RESULTS
Site record searches and Uterature reviews were conducted at the San Diego Museum of
Man data repository and at the South Coastal Infonnation Center at San Diego State
Umversity. These record searches resulted in the identification of one previously recorded
archaeological site SDi-10670 (W-117). Thi, site is on the north side of Palomar Airport
Road and adjacent to the project area. The site is located in the vicinity of Area 1 and is
only partiaUy within the pitjposed impact area. SDi-10670 (W-117) is recorded as a sparse
artifact and shell scatter which has been disturbed by agricultural activities (Rogers site
record form n.d.). An updated site form prepared by archaeologists from RBR &
Associates listed surface anifacts, on the north side of Palomar Airport Road These
artifacts were described as spUt cobble scrapers and flakes of various geologic materials
(Gross « al. 1987). The metates and "digging weight" or "large bead" noted on the
onginal site record fonn by Rogers, were not relocated (Gross 1987). It was not
uncommon for Rogers to collect unique or diagnostic artifacts for curation at the San Diego
Museum of Man.

FIELD METHODS AND RESULTS
3.1 SURVEY METHODS
Fieldwork was conducted by Andrew Pigniolo and Dennis Gallegos in October of 1987.
The survey mediods applied during die field investigation conform to tiie guidelines and
requirements of die Society of Califonua Archaeology (King et al. 1973) and tiiose outiined
by die National Park Service (Scovill et al. 1972).
Thc project areas were surveyed on foot at an interval of 5 m. as tenain and vegetation
pennitted. All areas were carefuUy examined for cultural debris, and road cuts and natural
drainages were checked for indications of subsurface archaeological deposits. Ground
visibiUty averaged 50 percent in bodi areas witii vegetation and soU fill obscuring the
ground surface in some areas.
3.2 SURVEY RESULTS
Field survey of Areas I and 2 resulted in die identification of an extension of archaeological
site SDi-10670 (W-117) widiin impact Area 1 and die location of one new cultural resource
site PAR-1 witiiin Area 2. The ponion of SDi-10670 extending witiun tiie cunent project
area consists of approximately 100 fragments of sheUfish remains including; Chione sp.,
Donax sp.. Mytilus sp.. Argopecten sp.. and surface anifacts. Additionally, sheUfish
remains were noted in a eartiien slope cut, adjacent to Palomar Airpon Road. The shcU
deposit was evident to a maximum depdi of 15 cm below die ground surface. Artifacts
coUected from die site surface include 19 flakes and/or fragments of angular waste and one
unifacial, riiyoUte mano fragment (Table 1). TTiese artifacts were mapped on a 1 "=40' map
prior to coUection and were cataloged according to die procedures accepted by local
instimtions. These anifacts are curated in die WESTEC Services Inc.. Cultural Resource
Laboratory.
Newly reconied site PAR-1 is witiiin impact Area 2 (see Attachment A for die site record
fonn submitted to San Diego State Umversity and die Museum of Man). This site is a sheU
midden witii a surface scatter of approximately 20 Udiic artifacts categorized as flakes and
angular waste. These artifacts were not collected. The site area measures approximately
180 feet EW by 120 feet NS, Based on erosional cuts the shellfish deposit appears to
3-1
extend to a depth of over 40 cm below the ground surface. The represented shellfish
spec.es « the madden are dominated by Chione sp. and Argopecten. sp. Portions of the
site has b^dut^bed by the dumping of soU fill, off site grading for a road widening, and
extensive roden, bunowing. TTie remainder of the site appears to be in good condition

SCOPE OF WORK
Palomar Airport Road Improvements
October 22. 1987
Task 1: Archaeology WESTEC will conduct an archaeological field
investigation for the detour road and channel improvements (800
feet+/- ) for Palomar Airport Road Expansion. The archaeology
report prepared for the Palomar Airport Road alignment project will
be amended to include the results of this reconnaissance.
Task 2: Biological Reconnaissance WESTEC will conduct a
biological assessment of the project site and update the Palomar
Airport Road alignment report. WESTEC will prepare an impact
analysis report suitable for submission to City Planning staff and
regulatory agencies (U.S. Army Corps of Engineers, California
Department of Fish and Game and California Coastal Commission).
Task 3: Conceptual Mitigation Plan WESTEC will prepare a
conceptual biological mitigation plan for impacts related to the entire
road alignment, channel and detour road project. WESTEC will
consult with the City to determine suitable areas for mitigation and
then prepare the conceptual plan for submittal to the City Planning
staff and regulatory agencies for support of permit applications.
Task 4: Agency Consultation WESTEC will coordinate with City
of Carlsbad staff and regulatory agencies for permit acquisition
support. Included in this task will be the preparation of applications
for the regulatory agencies and negotiations and consultations with
the agencies. WESTEC will meet with agency representatives, as
necessary, to support the mitigation program. This task will be billed
separately from the other tasks described above. The estimated
break-out for staffing allocation of time for this task includes 80
hours of Project Manager (B. Dehoney) and 30 hours of Staff Biologist
(P. Gordon-Reedy).
SCHEDULE
WESTEC will conduct the field reconnaissances within three weeks of
contract authorization. Mitigation plans and agency consultation will
follow.
COST PROPOSAL
WESTEC's cost estimate for this scope of work is as follows:
Task 1: Archaeology $ 500
Task 2: Biological Reconnaissance $2000
Task 3: Conceptual Mitigation Plan $3000
Task 4: Agency Consultation $4500
WESTEC will not exceed $10,000 without specific authorization by the
City of Carlsbad.
WESTEC's offer to complete the scope of work and cost estimate may
be accepted at any time within the next 30 days. After that date, the
cost estimate may need to be revised to reflect possible increased
expenses.
ADDITTONAL WORK
Any effort to accomplish additional work beyond the aforementioned
tasks can be handled through a supplemental agreement. If the
agency consultation task experiences complications and man hours
expended exceeds that estimated above, a supplemental agreement
will be required. Also, if agency meetings and/or hearings are held
outside the San Diego/Los Angeles area costs associated with travel
will either be provided by the City or as added costs.
